in Hopper-{Dara of which the following is a specification;

' @ur invention relates to improvements in hopper cars especially of the twin type, and has particular reference to the construction ofa cross hood and the means for reinforcing the some and of securing it at its ends to the center girder and sides of the car.

in the drawings which are hereto attached and hereby made a part of this specification, Figure 1 is a vertical longitudinal section through one end of the car taken on a. line between the center sill and side of the car,

' nection thereof with the center sill.

showing our improvements; Fig. 2 is a vertical transverse section through the car near one end between the end-slope sheets and cross hood along the line A A of Fig. 1; Fig. 3 is a side View of the reinforcing diaphragm or cross bearer indicated at 38 in Fig. 1 showing the connection thereof with the center sill and the side of the car, the

cross hood'being omitted in this view and other features. Fig. i is a top plan view of the cross hood illustrating especially the con Fig. 5 is an enlarged detail of the cross hood in vertical transverse section, between the center sill and side of the car with the reinforcing diaphragm shown in place, said figure showing essentially the cross hood features of Fig. 1 ,gnly on a larger scale.

in the drawings, 1 is the centersill construct-ion, formed, in this instance, of parallel channels having their flanges inwardly disposed; 2 indicates the end slope sheets, 3 is the side of the car, 4 is the center sill hood extending longitudinally of the car, and secured at end 5 to the end slope sheets, in a. well known manner, and at the cross hood it is secured in a r anner hereinafter described. An outside side stake of the car is shown at 6, and the angle 7 is connected thereto through the side of the car near the bottom thereof at 8, and at the top of the car is likewise provided an angle 9 which is secured at 10 through the side 3 of the car and flange 1]. oftheoutside side stake 6; likewise,- secured to the side 3 of the car and L IRWI andoutside stake 6, is the inside side stake formed of the member 12 having the flange .13 thereon through which rivets 14 secure the same to'the side of the car, and having the wide flange 15 thereon extending inwardly, and hereinafter more fully described; the second member 16 and the member 12 are connected as shown at'17, the member 16 being riveted to the side of the car at 18 through its flange l9.

Extending from the sides of the car to the center Slll is a hood formed of a single sheet of metal, folded as shown at 20, to form the vertical sides having an interval between the same, and having the downwardly diverging sides 21 and :22; or if preferred, two sheets of metal. may be employed, shaped so as to form the hood as here shown, meeting along their upper edges, where, as above described, the fold is formed in the single sheet. Upon the lower edge of each of these diverging sides is secured an angle 23, riveted thereto as shown at 24, the said angle extending from the outer edge of the sheet 21 to the center sill 1. The angle 25 is applied to the center sill and the cross hood sheet 21 to unite these members, and is riveted to both as shown at 26 and 27. To connect the cross hood and center sill hood, we provide the tie or saddle member 28, which overlies the ridge 20 and. the inner ends of the cross hood sheets and is secured thereto as shown at 31;

said member 28 is formed with the flange portions 29 thereon overlying the center sill wardly at their lower ends to take over theridge of the cross hood,\vl1ereby the cross hood is strongly reinforced against stresses operating both transversely and longitudinally of the car. through the inside side stakes, the folded or vertically flanged portion of the cross hood The rivets 37 extendsheet, and the diaphragm reinforcing memher now to be described.

Referring especially to Fig. 3, a cross bearer or diaphragmreinforcing member 38 is provided, flanged atits inner end and lower edge, and is secured at 39 through its inner end flange to the vertical web of the center sill; and through its lower edge flange ll, said diaphragm 38 is secured by the rivets 42 to the compression member 48, which is arranged transversely ofthe center sill and secured thereto at 4.4. Said diaphragm member 38 is secured at itsouter end to the side 3 of the car by means of an angle member e5 which is ap lied to the diaphragm member and the sid and secured thereto at 4:6 and 47, the rivets 47 passing through the said angle and the side of the car and the flange 48 on the outside side stake. The angle 45 at its lower end is bent to overlie flange 50 of angle 49 secured at 51 upon the lower edge of the side 3 of the car. A tension member 52, which in the present instance is an angle,is applied transversely to the upper flanges 53 and 54 of. the center sill, and securely riveted thereto at 55 and 56; at 57 said tension member is secured to the cross bearer or diaphragm reinforcing member 38, and on the opposite side of the center sill the tension member is similarly secured as at 58, to the o1 po'site dia 'ihragm member. The compression member as is secured to the lower flange ot' a similar diaphragm reinforcing member is not herein shown, on the opposite sine of the center sill, being simi-.

lar to the diaphragm member 38 in all respects.

Referring esp cia-lly to Fig. 5, it is seen that the upper edge or" the diaphragm member 38 lies within the told 20 ot the upper portion the cross hood sheet, and is secured to the ertical sides thereof by means of rivets shown at 59. In this manner the cross hood is supported from beneath, and, as descrihed we, is united to the center sill and the side of the car and to the compression tens n members described,

whereby the (JOllS Ll'LlCLlU-D of the car at this point is strongly reinforced; the reinforcing diaphragms on opposite sides of the center sill are securely tied together as stated above; further, the cross hood is greatly reinforced at its junction with the center sill hood by means of the saddle or tie member 28, and the stresses set up in this region of the car by its operation are efliciently absorbed.

Many advantages accrue in operation from our con'ihination of the style ofcross hood herein described with the reinforcing diaphragm, and we do not desire to confine ourselves to the specific construction shown, but desire to have the advantage of all variations d changes which lie within the scope o "3 appended claims.
